...WET WEATHER AND POSSIBLE FLOODING TO CONTINUE THROUGH SUNDAY
FOR PORTIONS OF THE SOUTH...

...STRONG STORMS AND POSSIBLE FLASH FLOODING FOR PARTS OF THE
NORTHERN PLAINS ON SUNDAY...

...RELIEF FROM THE HEAT FOR PARTS OF THE WEST INTO THE PLAINS...

WARM AND HUMID CONDITIONS WILL REMAIN FOR LOCATIONS TO THE SOUTH
OF A WEAKENING, QUASI-STATIONARY FRONT, EXTENDING WESTWARD FROM
THE MID-ATLANTIC TO THE MIDDLE MISSISSIPPI RIVER VALLEY. GIVEN
LOCATIONS FROM ARKANSAS THROUGH NORTHERN MISSISSIPPI, ALABAMA AND
INTO THE SOUTHERN APPALACHIANS HAVE BEEN ANOMALOUSLY WET OVER THE
PAST WEEK, ANY ADDITIONAL RAIN MAY CONTRIBUTE TO MORE FLOODING AND
FLASH FLOODING. BY MONDAY, THERE WILL BE LESS UPPER LEVEL SUPPORT
FOR HEAVY RAIN DOWN ACROSS THE SOUTHERN U.S., WHICH SHOULD ALLOW
FOLKS TO BEGIN DRYING OUT FROM RECENT HEAVY RAIN.

TEMPERATURES WILL CLIMB WELL INTO THE 90S FROM EASTERN MONTANA AND
WYOMING INTO THE CENTRAL AND NORTHERN PLAINS TODAY, BUT THE
PASSAGE OF A STRONG COLD FRONT WILL DROP HIGH TEMPERATURES FOR
THESE LOCATIONS INTO THE 70S FOR SUNDAY. HOWEVER, LOCATIONS INTO
PORTIONS OF THE DAKOTAS AND MINNESOTA WILL HAVE TO DEAL WITH A
BOUT OF STRONG TO SEVERE STORMS WITH POSSIBLE FLASH FLOODING LATE
IN THE DAY SUNDAY AS THE COLD FRONT MOVES THROUGH BEFORE RELIEF
FROM THE HEAT CAN WILL BE SEEN. THE COLD FRONT WILL CONTINUE SOUTH
AND EAST ON MONDAY INTO PARTS OF THE UPPER MIDWEST AND THE PLAINS
BRINGING POSSIBLE STRONG/SEVERE STORMS WITH IT, WITH MUCH COOLER
TEMPERATURES IN THE WAKE OF THE FRONT.

ACROSS THE WESTERN U.S., LITTLE RELIEF FROM THE HEAT WILL BE SEEN
FOR PORTIONS OF THE INTERIOR NORTHWEST, WHERE HIGH TEMPERATURES
NEAR 100 DEGREES WILL AGAIN BE SEEN FOR PARTS OF THE COLUMBIA
BASIN THROUGH TUESDAY. THIS IS DUE TO A RELATIVELY BLOCKED PATTERN
ACROSS THE WEST, WHICH WILL ALSO FEATURE SCATTERED, DIURNALLY
DRIVEN THUNDERSTORMS ACROSS THE ROCKY MOUNTAINS AND DESERT
SOUTHWEST.
